Bleeding loader hydraulic system

Have M with pump that runs off of the distrubutor with a Westendorf loader. First everything worked fine before rebuiding the lift cylinders except they leaked. Found the system had water in it so drained the entire system. Now none of the cylinders will do anything and you cannot hear the tractor bog down at any time when moving the valves. OKay I know there is air in the entire system so how is the best way to bleed the air out of it. Was doing it at the cylinders, but is there a better/faster way to do it? Thank you for any help.

Maybe late for this but it would help to get the pump lower if you can. Distributor pumps are kinda high relative to their reservoir. The biggest problem is keeping the reservoir topped up while moving oil into the cylinders. If it runs out then your pumping air and the process gets all foiled up with foamed oil. Never let it do that. Extend a little, add oil. If a ram quits moving, don't try to force it. It's not getting oil.

Thanks for the suggestion! I kept filling the reservoir with oil and it started to work. I did not have enough oil in the system even though the tank had fluid in it. Was planning on draining the system again and did not want to put to much oil it. I guess now I know exactly the amount of oil the system needs to function.

Planning on buying parts, owner’s and shop manuals. Any suggestions on publisher? Knowledge is power literally.
